Hey Everyone I am 16 and I started riding not too long ago so still learning everything. I had a new battery placed into my bike not too long ago since I had a dead battery after the bike sat for a long time in the shed. I was riding my bike today and it started fine and went down to a different town I stopped and decided to rev the engine for a bit while waiting for someone I turned the engine off to save some fuel and once I had to start it again it was taking a long time to start I first thought maybe my battery was low so I travelled back to my town which is about 25KM away and shut it off and tried starting it again and it started cranking and wouldn't start the first time I tried again the 2nd time and after a while of cranking it started. I am thinking it might be the spark plugs it has driven almost 8000KM. I am guessing the last owner of this bike hasn't changed the spark plugs since he got it.
